cocos2d-x 3.0 rc0 : develop for android in eclipse - android

I'm on windows xp & Eclipse Kepler. I want to develop with cocos2d-x, but I have some problem.
First, I created project.
cocos new MyGame -p com.myprog.MyGame -l cpp -d MyGame
and I tried run:
cd MyGame
cocos run -s MyGame -p android
and it succeeded.
The problem happens when I open it by eclipse. I create eclipse project, Android Project From Existing Code.
But I can't know what to do next.. even I don't know how to build! (Project - Build doesn't work..)
Moreover, Classes, cocos2dx, extensions and scripting folder are broken..
I tried to find solution, but people are saying about only cocos2d-x 2.x ...
Even if README.md seems to say about 2.x!
Could anyone tell me how do I do?

Installation Process:
Cocos2d require NDK and Cygwin
First install NDK ->

Cocos 2d installation link:
http://www.cocos2d-x.org/wiki/How_to_set_up_the_android_cocos2d-x_development_environment_on_Windows_7
Download cocos 2d version and follow the instruction in above link
This packages you required in cygwin: search and install:
autoconf, automake, binutils, gcc-core, gcc-g**, gcc4-core, gcc4-g**, gdb, pcre, pcre-devel, gawk, make
After installation cygwin,ndk and you need to config in C/C++ preference in eclipse(Don't forget to install c/c++ plugin in eclipse)
My NDK and PATH is :
NDK_ROOT->C:/android-ndk-r9c
PATH->C:\android-ndk-r9c;C:\Cygwin\bin;
Then import the sample project :
cocos2d-x-2.2.2\samples\Cpp\HelloCpp\proj.android
Import the library :
cocos2d-x-2.2.2\cocos2dx\platform\android\java
Add the library to hello world project
when you import hello world project eclipse automatically include the header files:
bash F:/cocos2d-x-2.2.2/samples/Cpp/HelloCpp/proj.android/build_native.sh
cygwin warning:
MS-DOS style path detected: F:\cocos2d-x-2.2.2\samples\Cpp\HelloCpp\proj.android
Preferred POSIX equivalent is: /cygdrive/f/cocos2d-x-2.2.2/samples/Cpp/HelloCpp/proj.android
CYGWIN environment variable option "nodosfilewarning" turns off this warning.
Consult the user's guide for more details about POSIX paths:

make: Leaving directory '/cygdrive/f/cocos2d-x-2.2.2/samples/Cpp/HelloCpp/proj.android'
After get output in console right click project and goto properties and choose paths and symbols under c/c++ general
Run the project and you can see the output :

You can handle it in different way though you are on windows you have to use Microsoft Visual Studio Express 2012 for Windows Desktop its free and also it will give you good IntelliSense support.
Every time you edit using MS VS2012 run proj.android/build_native.py and then you can run your app from eclipse as usual.

PowerVR Android sample: makefile not working

I'm having a hard time setting up PowerVR SDK for Android on Windows 8 64, assuming I met all requirements:
Android SDK (fresh Eclipse)
Android NDK
Cygwin (with make)
PowerVR Android SDK 3.0
I can perfectly make and run an Android NDK sample. However, the same process fails for building any PowerVR sample (from the SDK). Here's the output when I try to run the makefile:
$ ndk
Compile++ thumb : OGLES2Texturing <= OGLES2Texturing.cpp
arm-linux-androideabi-g++.exe: error: C:/cygwin///cygdrive/c/Users/stfn/workspaces/android/03_Texturing/jni/OGLES2Texturing.cpp: No such file or directory
arm-linux-androideabi-g++.exe: fatal error: no input files
compilation terminated.
/cygdrive/c/android-ndk-r8d/build/core/build-binary.mk:269: recipe for target `obj/local/armeabi/objs/OGLES2Texturing//cygdrive/c/Users/stfn/workspaces/android/03_Texturing/jni/OGLES2Texturing.o' failed
make: * [obj/local/armeabi/objs/OGLES2Texturing//cygdrive/c/Users/stfn/workspaces/android/03_Texturing/jni/OGLES2Texturing.o] Error 1
I suppose the error should be related to a wrong path given to the compiler. To me it looks like a mixture of standard Windows and Cygwin/Unix paths: * C:/cygwin///cygdrive/c/Users/stfn/...*
If been through so many makefiles now trying to resolve this issue but I just don't know where else to look. This is the first time I tried messing with the NDK. I'm afraid this could be my last.
Any help would be greatly appreciated
1.in the Android.mk file, for the PVRSDKDIR, set the path of your project folder in your workspace.
2.Copy the build, tools, and shell folders from the powervr sdk folder to your project folder

How to build libav using ndk-build in cygwin for windowds?

I want to know how to build libav on windows7 using cygwin. I've tried the following steps :
1-change the directory using cd command to libav_file_directory/android(android folder is empty where the .so file will be saved as far as my knowledge is concern).
2-execute the ./ndk-buil command.
I got the following as result:
*Android NDK: Could not find application project directory !
Android NDK: Please define the NDK_PROJECT_PATH variable to point to it.
/cygdrive/c/Users/balwant.singh.TA/Desktop/Android/android-ndk-r8/build/core/build-local.mk:130: * Android NDK: Aborting . Stop.*
plese reply with solution, and also I want to know which all android media player uses the libav as their native code.
1.)Set all your paths(Java_Home
2.)Set NDK_HOME to Ndk-Build Path
3.)Run Cygwin
4.)GO to project Library path
5.)Run make command
6.)then Run ndk-build

Android ndk-build command does nothing

I have a similar question to that posted here:
Android NDK: why ndk-build doesn't generate .so file and a new libs folder in Eclipse?
...though I am running Windows 7, not Mac os. Essentially the ndk-build command is run, gives no error but doesn't create an .so file (also, since I'm on windows this should create a .dll and not an .so?). I tried running the command from the root, jni, src folders etc. but got the same result; cmd just returns to the prompter after a few seconds. I ran it again from the jni folder with NDK_LOG=1 parameter to see what was happening. Here is a portion of the transcript of the log results after running ndk-build in the jni folder (after it successfully identified the platform, etc.)...

Set up a builder. Refer to following article for how to do that:
http://maxters.net/2011/02/android-ndk-builder-for-eclipse-in-windows/
There is a "small" change beginning NDK r8 – Cygwin is not necessary anymore and I had a trouble when building native libraries with Cygwin and NDK r8 – there was some error message about cxx-stl...
Almost everything in the link above is OK, but leave Arguments in the Main tab blank and change Location to:
${env_var:ANDROID_NDK_ROOT}/ndk-build.cmd
I use system variable path ANDROID_NDK_ROOT, but you can provide a full path to the ndk-build.cmd.
Also, there is no need to set any variable in the Environment tab.
Set up your builder this way and you will be fine.
Just a note, Android is built on the top of the Linux OS, so even if you are on Windows you will get Linux libraries with .so extension.
Following link was instructive but missing a detail if you are configuring NDK support in Eclipse after CDT it already depricated (summer of 2017 already).
http://maxters.net/2011/02/android-ndk-builder-for-eclipse-in-windows/
Where you need to configure your external builder Location, instead of pointing to cygwin\bin\bash.exe and adding as Argument your ndk-build.cmd location this is what worked for me on Windows 7 and 10.
In "Edit Configuration" dialog for external builder do following:
- for Location -> specify where your "ndk-build.cmd" is. i.e "D:\Android\NDK\ndk-build.cmd"
- for Arguments -> just specify "all"
The NDK build system relies on wildcards to find the sources to compile. If you have a path wrong somewhere, it will find no sources and do nothing. Check Android.mk very carefully. More can't be said unless you post Android.mk and a description of the source tree.

Building FIPS module for android

I am working on an android project that requires the cryptographic libraries that are present in the application to be FIPS certified. To my knowledge there are no FIPS validated JAVA security libraries. Boucy Castle is good but its not validated. After reading some forum posts, I found out that OpenSSL's FIPS module can be used with the help of NDK.
Right now I am trying to build the fips-openssl module for Android, to do that I have created a script for the environment variables for cross compiling.
I am using openssl-fips, and ndk-r8 for this project. I followed the fips guideline I found on google. I hope this gives a clear picture of what I am trying to do.
#! /bin/sh
export ANDROID_NDK="~/Android/android-ndk-r8"
export FIPS_SIG="${ANDROID_NDK}/incore"
export GCC_C1="/usr/lib/gcc/i686-pc-linux-gnu/4.7.0/"
export PATH=$PATH:"${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin";
export MACHINE=armv71
export ARCH=arm.
export CROSS_COMPILE="arm-linux-androideabi-"
export SYSTEM=android
#export RELEASE=2.6.32.GMU
export ANDROID_DEV="$ANDROID_NDK/platforms/android-14/arch-arm/usr"
export HOSTCC=/usr/bin/gcc
when doing the make this is the error that i get.
arm-linux-androideabi-gcc: error trying to exec 'cc1': execvp: No such file or directory
make[1]: *** [cryptlib.o] Error 1
make[1]: Leaving directory `/home/abhiram/fips/openssl-fips-1.2.3/crypto'
make: *** [build_crypto] Error 1
When i do a "find", the cc1 executable is present in this specific directory.
find . -name cc1
./toolchains/mipsel-linux-android-4.4.3/prebuilt/linux-x86/libexec/gcc/mipsel-linux-android/4.4.3/cc1
./toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/libexec/gcc/arm-linux-androideabi/4.4.3/cc1
./toolchains/x86-4.4.3/prebuilt/linux-x86/libexec/gcc/i686-android-linux/4.4.3/cc1
Looks like the problem is in the export statement, there is a blank space where a dash should be in the PATH line. Change this:
export PATH=$PATH:"${ANDROID_NDK}/toolchains/arm-linux-androideabi 4.4.3/prebuilt/linux-x86/bin";
to this:
export PATH=$PATH:"${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin";
Also, your find shows that the cc1 executable is not in the path, so add its location to the path export as well:
export PATH=$PATH:"${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin":"${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/libexec/gcc/arm-linux-androideabi/4.4.3/";
Right now I am trying to build the fips-openssl module for Android, to do that I have created a script for the environment variables for cross compiling.
OpenSSL provides a script for Android, if you are interested. You can find it on the OpenSSL wiki: FIPS Library and Android.
when doing the make this is the error that i get:
arm-linux-androideabi-gcc: error trying to exec 'cc1'
It looks like your PATH does not include the cross-compile toolchain.
How are you invoking the script? You need to include a leading dot (".") to ensure the changes are applied to the current shell (and not the sub-shell that executes the script (which simply exits)).
Here' the first step of OpenSSL's build procedures for Android located at FIPS Library and Android. Notice the leading dot:
$ . .setenv-android.sh
The results of running the script set a bunch of variables used by the OpenSSL build system:
$ . ./setenv-android.sh
ANDROID_NDK_ROOT: /opt/android-ndk-r9
ANDROID_EABI: arm-linux-androideabi-4.6
ANDROID_API: android-14
ANDROID_SYSROOT: /opt/android-ndk-r9/platforms/android-14/arch-arm
ANDROID_TOOLCHAIN: /opt/android-ndk-r9/toolchains/arm-linux-androideabi-4.6/prebuilt/darwin-x86_64/bin
FIPS_SIG:
CROSS_COMPILE: arm-linux-androideabi-
ANDROID_DEV: /opt/android-ndk-r9/platforms/android-14/arch-arm/usr
"${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/libexec/gcc/arm-linux-androideabi/4.4.3/"
I don't believe this is needed.
export ANDROID_NDK="~/Android/android-ndk-r8"
According to the folks on the Android NDK user list, you should set both ANDROID_NDK_ROOT and ANDROID_SDK_ROOT. The various NDK and SDK tools use those environmental variables. I suppose the SDK value would be "~/Android/android-sdk" for your installation.
See Recommended NDK Directory? for details.
I also think you should be using ANDROID_SYSROOT. Its not used by the NDK or SDK tools; rather, its used by OpenSSL and passed as sysroot during compile.

Error with building Android NDK Project

I wand build project in windows, I get same Errors:
bash C:\linux\android-ndk1\ndk-build V=1

Why this happened?
From: http://developer.android.com/sdk/ndk/overview.html#reqs
Required development tools
For all development platforms, GNU Make 3.81 or later is required. Earlier versions of GNU Make might work but have not been tested.
A recent version of awk (either GNU Awk or Nawk) is also required.
For Windows, Cygwin 1.7 or higher is required. The NDK will not work with Cygwin 1.5 installations.
Meaning, that you will have to install Cygwin. After that you can call the ndk-build like:
$ProjectPath> /cygdrive/c/myNdkPath/ndk-build
Please also check the "Getting Started" part of:
http://developer.android.com/sdk/ndk/index.html
